Helper subtemplate

Syntax
{{Diff/translator|label|url=diff URL}}

In order to make the {{Diff}} template simpler to use this helper subtemplate is available, to be used only in the preview window.

For instance, imagine you want to refer to the following diff URL: https://en.wikipedia.org/w/index.php?title=Main_Page&diff=139993&oldid=139992&diffonly=1; you only need to transcribe that URL in this subtemplate and produce a preview, without saving the page:

{{Diff/translator|Sic exorsi sumus|url=https://en.wikipedia.org/w/index.php?title=Main_Page&diff=139993&oldid=139992&diffonly=1}}
{{Diff|Main Page|139993|139992|Sic exorsi sumus|diffonly=yes}}

Now copy the code generated ({{Diff|Main Page|139993|139992|Sic exorsi sumus|diffonly=yes}} into the edit window where {{Diff/translator}} was and publish the page.
